I have a large sub that controls a web browser address dependent on the
active cell! this is triggered by a selection change event. if this has been
trigered prior to a sheet change excell crashes as soon as the sheet change
takes place if it hasnt been trigered then it doesnt.
The web browser is placed on the main page not on a user form, if I make
this not visible through the proporties menu it doesnt crash but if I select
visible = false as a command prior to sheet change it still crashes!
Im using 2003 on XP have installed SP3.
Its a pretty big sub but it works brilliantly just so long as you dont want
to change sheet!! The upper half of the sub controlls the web browser address
and the lower part triggers user forms, but its definately the web browser
that is causing the crash!
